I'd like to learn about SVM, HMM and wavelet algorithms in their usage in bioinformatics. I have a somewhat rudimentary understanding of the underlying mathematics from Wikipedia and a couple other sources, but I find that a concrete demonstration of their application fleshes it out. Are there texts, software packages (preferably free) or papers you'd recommend that: 1) includes good starter problem sets, or; 2) demonstrates how these techniques are used in research applications (beyond "we used xyz here"). Thanks!

If you were to buy just one text on probability and statistics (and their applications) that covers the subjects in some depth (building from an introductory college level, through advanced undergraduate to a graduate level and perhaps further) and does a good job of making the basic concepts clear with solved examples (employing those drawn from actual research), which one would you choose?

Are national political polls that make use of random sample populations adjusted to account for the differences in overall population distribution throughout the US (in other words, do national political pollsters typically use some methodology to appropriately weigh responses from poll respondents depending on whether they live in more densely or less densely populated regions)?
